This book contains the contributions presented in the 5th WDK Workshop on Product Structuring in Tampere, Finland, in February 2000. Special theme was Design for Configuration. Besides the papers it includes developed summaries from the discussions of the expert group. Thus, the book provides the reader with a review of the latest discussion in the ongoing process of Product Structuring. Even though the meeting was of academic nature, the papers include many practical examples of industrial applications. In order to give a comprehensive picture of the aspects of Design for Configuration the papers are organised in four sections: - Analysis of customers, markets and technology; - Development of product portfolios and module systems; - Metrics and methods for modularity and configurability; - Supporting modeling and IT-tools. This book is the first publication of the newly established Design Society.Naccache, David is the author of 'Topics in Cryptology, Ct-Rsa 2001 The Cryptographers' Track at Rsa Conference 2001, San Francisco, Ca, Usa, April 8-12, 2001 Proceedings', published 2001 under ISBN 9783540418986 and ISBN 3540418989.
